Staying at my Step-Grandparents House makes Step-Grandma smile ( PART 3 )

I have a job interview in the same city that my step-grandparents live in so i promised my stepmom to stop by and see them. we visit for a while, and i tell them that i have to go find a motel for the night so i can be fresh for the interview in the morning. well, my step-grandparents wouldn't hear of me staying anywhere but with them. i figured it would save me a few bucks so what the heck.. i put my stuff in their guest room and i laid on the bed to take a nap. suddenly i was felling horny so i took out my pud and started to wack off. just when i was really getting into it, both of my step-grandparents came into my room. i quickly covered myself up but they knew what i was doing. to my surprise my step-grandfather said they wanted to talk to me about something that involved sex. little did i know that they were going to want me to have sex with my step-grandma. it seems like my step-grandfather was having performance issues and my step-grandmother was really hot for a good fucking. after him mulling around, my step-grandfather strips and feels up her up in front of me. i have to admit i was turned on seeing my step-grandmother’s soft white breasts. she grabbed my cock with her hand and started to stroke and suck me. when i was fully erect, she climbed aboard my hard cock and rode me. she fucked pretty darn good for a woman her age and i pounded her pussy the best way i know how. i was close to cuming so i had her get on her knees and i fucked her mouth until i put a big load in it. she let some of my cum flow over her lips onto her tits.
